Background: Soil-Transmitted Helminth (STH) infections remain a significant public health problem in tropical regions, particularly in areas with poor sanitation and susceptibility to flooding. Evaluating STH control programs is essential to measure the effectiveness of interventions.

Objective: To evaluate the effectiveness of the mass deworming program in reducing STH prevalence among primary school children in flood-prone areas.

Methods: An analytical observational cross-sectional study was conducted in Umatoos Village, Malaka District, from September to October 2025. The sample consisted of 194 primary school students (from SDK Umatoos, SDI Beilout, and SDK Loomota) selected from a population of 311 students. Stool samples were examined microscopically using the 2% Lugol method to detect STH infections. Risk factor data were collected using a structured questionnaire. Descriptive data analysis was performed using SPSS version 25.

Results: None of the 194 stool samples examined tested positive for STH, resulting in a prevalence of 0%. A total of 85.6% of respondents reported taking deworming medication regularly every six months. Hygienic behavior indicators showed that 91.2% washed their hands before meals, 95.4% washed their hands after defecation, 73.7% trimmed their nails regularly, and 87.1% consistently wore footwear. Environmental sanitation conditions were relatively good, with 93.3% of households having latrines and 93.8% using piped water or well water.

Conclusion: The mass deworming program implemented consistently since 2016, combined with good personal hygiene practices and adequate environmental sanitation, successfully achieved zero STH prevalence among primary school children in flood-prone areas. These findings support a comprehensive approach integrating medical interventions and behavioral changes in controlling neglected tropical diseases.
